Ainz watched as the group of guards, who were armed to their teeth, broke through the first line of defense easily, and began to engage with Sam's men.
Ainz held his spear, and picked a target, with a heavy hammer.
He leisurely sent a wind slash at his target following it with another wind slash to deliver a melee attack, the guard tried to block it but was forced backward by the attacks.
The guard shattered the attack with the sheer strength of his hammer, while swinging his hammer at Ainz, who casually swung the hammer away with the tip of his spear.
CLINK!
The guard turned in his direction, and was surprised to see that it was none other than a kid who had blocked his attack, but most importantly he did that casually, while maintaining his position!
It could be said that Ainz had never actually fought against a real cultivator by himself, since he was always hiding his true power, but it didn't mean he couldn't kill one.
